• Develop, test and deploy detection content across Microsoft Sentinel and Splunk SIEM.
• Write and optimise detection logic using KQL and SPL.
• Turn monitoring requirements and use cases into effective, actionable detections.
• Tune alerts to reduce false positives and improve SOC efficiency.
• Validate detections against telemetry and ensure accuracy.
• Support onboarding of log sources across cloud, infrastructure, identity and network.
